Cerebral networks linked to the event-related potential P300 [PDF]

European Archives of Psychiatry and Clinical Neuroscience, 2003
P300 is an event-related potential that is elicited by an oddball paradigm. In several neuropsychiatric diseases, differences in latencies and amplitude compared to healthy subjects have been reported. Because of its clinical significance, several investigations have tried to elucidate the intracranial origins of the P300 component.

Auditory P300 Event-Related Potentials in Fibromyalgia Patients

Yonsei Medical Journal, 2003
This study assessed the cognitive brain function measured by the cognitive P300 auditory event-related potentials (ERPs) in female fibromyalgia (FM) patients and compared the results with those from healthy age and education-matched controls. The relationship of the P300 potentials to the pain threshold of patients was also investigated.

Intracranial potentials correlated with an event-related potential, P300, in the cat [PDF]

Brain Research, 1985
Intracranial recordings of long-latency, event-related potentials were obtained from paralyzed, artificially respirated cats. A modified oddball paradigm was employed in which cats were presented with a randomized series of two tones, a 'frequent' 4 kHz stimulus and a 'rare' 1 kHz stimulus.

Auditory Event-Related Potential (P300) in Patients with Schizophrenia

Medical Journal of Babylon, 2021
Background: Schizophrenia is a psychiatric disorder characterized by multiple symptoms such as positive symptoms, negative symptoms, and cognitive symptoms. Cognitive deficit can be detected with specific neurophysiological tests.

MTL-P300 as a marker of the epileptogenic zone and hippocampal functionality in the presurgical evaluation of temporal lobe epilepsy: a systematic review

Arquivos de Neuro-Psiquiatria, 2022
Background In the past twenty years, there has been an increasing interest among neuroscientists and physicians in mapping the cortical areas involved in the epileptogenic zone (EZ) through event-related potentials (ERPs) that enable the evaluation of ...

Neurochemical substrates and neuroanatomical generators of the event-related P300 [PDF]

, 1999
The present review focuses on the current knowledge of the neurochemical processes and neuronal structures involved in the generation of P300. The increasing knowledge in this area facilitates the physiological interpretation of P300 findings as well as ...

Event-related potential (P300) in epilepsy

Acta Neurologica Scandinavica, 1990
The P300 component of auditory event-related potential was studied in 39 patients with temporal lobe epilepsy (TLE), 26 with idiopathic generalized epilepsy (IGE) and 28 controls. The age-corrected P300 latencies were significantly longer in TLE patients compared with those in IGE patients and controls.

Abnormal P300 in people with high risk of developing psychosis [PDF]

, 2008
Background Individuals with an “at-risk mental state” (or “prodromal” symptoms) have a 20–40% chance of developing psychosis; however it is difficult to predict which of them will become ill on the basis of their clinical symptoms alone.

The cost of space independence in P300-BCI spellers. [PDF]

, 2013
Background: Though non-invasive EEG-based Brain Computer Interfaces (BCI) have been researched extensively over the last two decades, most designs require control of spatial attention and/or gaze on the part of the user. Methods: In healthy adults, we
